Slow your roll killer.
@DZ nailed it.
Before you start dropping coin on personal gear, you should get some real experience using issued kit. FSBE II was solid. Most guys in my platoons did
not buy their own vests. But how can you know if it works for you before you've really used it?
Not only that, but do you know what platoon you're going to? What if you end up doing green side R&S? Your vest and belt won't be doing you any good then.
And even if you determine issue kit isn't for you, you need to try out some buddies' personal stuff to see what different styles feel like and how they work out. And there's always the possibility that someone in your chain of command mandates the use of issue kit in part or totality. This isn't unheard of.
Long story short, I would advise against buying any kit. The guys are getting some gucci kit these days. You may want to wait and see what you get in your issue at 2nd Recon. Don't be so swift to ditch the standard/norm and do your own thing that you come off as an attention seeker or know it all or too cool for school.
